fireman's pole
A fireman's pole (also called a sliding pole, firepole, or tom) is a wooden pole or a metal tube or pipe installed between floors in fire stations, allowing firefighters responding to an alarm to quickly descend to the ground floor faster than by using a standard staircase.
The device was invented in the 1870s by David Kenyon, in Chicago, Illinois, although it is often incorrectly credited to the Boston Fire Department.
== Overview ==
Firefighters usually remain above the ground floor of fire stations until they receive a call for help, after which they descend, don their firefighting gear, and board the fire engine as quickly as possible. Until 1878, spiral staircases or sliding chutes were common, but not particularly fast. Fire houses were also equipped with spiral staircases so the horses would not try to climb the stairs into the living quarters. The fireman's pole allows firefighters to move down much more quickly, although it is not suitable for climbing up. The pole connects the ground floor to the ceiling of the floor above through a hole in the ground floor ceiling. To use a pole, a firefighter puts his/her arms around it, steps into the hole, and uses his/her legs to control the speed of the descent, somewhat similarly to the technique used for fast-roping.
